'Rejuvenation' Nam Roi pomelo - increase economic efficiency

In fact, many pomelo orchards of 10-30 years of age are inferior to the risk of being cut off, causing the area of ​​planting Nam Roi pomelos - one of the key crops and specialty of Hau Giang province , has plummeted . Engineer Ngo Minh Long, Deputy Head of the Agriculture and Rural Development Division of Chau Thanh District (Hau Giang) has researched and implemented the topic of 'Rejuvenating Nam Roi pomelo trees 10-30 years old in combination with treating in-situ flowering. desired location ".

Successfully experimenting with 'rejuvenation' of pomelo trees, engineer Long has replicated this form for 3,600 households planting 1,500 ha of pomelo Nam Roi, bringing economic efficiency to many gardeners.

Pomelos

To implement 'rejuvenation' of pomelo trees, people cut off the branches on the tops and old branches in each stage.

In the first year, cut 30% of the branches on the tree, remove the old branches and branches that are in the canopy until the sun shines out.

The second year continues to cut 30% of the old fruitless branches to lower the height of the tree and help the plants provide nutrients for healthy branches.

The third year continues to cut old branches to lower the altitude and cut the foliage of the branched branches.

After cutting branches, grapefruit trees will grow many young shoots, need to keep the big shoots strong, oriented horizontally to make branches.

Treat flowering at the desired location by cutting off branches growing from the middle of the stem, after 1-2 weeks the branch is inhibited and flowered.

Need to choose suitable cutting position to produce fruits that are full of nutrients, grow well, big and beautiful, located at a moderate height so that growers can easily take care of, get quality pomelo fruit, meet export demand. Export through the European market.

Engineer Ngo Minh Long said that after implementing the 'rejuvenation' process, after three years, Nam Roi pomelo garden 10-30 years old will grow again like 4-6 year old pomelos, the height decreases from 10m down to 3-4m, thick and beautiful canopy, strong tree, double productivity.

This solution contributes to reducing the cost of cutting old grapefruit orchards for planting new pomelos or oranges, and retaining pomelo growing areas to meet the quantity of Nam Roi pomelo exported to other countries.

This is a new solution, first applied on Nam Roi pomelo in Hau Giang province, initially achieved efficiency.
